"Terminfo is a library and database that enables programs to use display terminals in a device-independent manner."	"The original (and most common) implementation of the terminfo library retrieves data from a directory hierarchy. By using the first character of the name of the terminal description as one component of the pathname, and the name of the terminal description as the name of the file to retrieve, the terminfo library usually outperforms searching a large termcap file."	0
"Terminfo was included with UNIX System V Release 2 and soon became the preferred form of terminal descriptions in System V, rather than termcap (which BSD continued to use). This was imitated in pcurses in 1982–1984 by Pavel Curtis, and was available on other UNIX implementations, adapting or incorporating fixes from Mark Horton. For more information, refer to the posting on the comp.sources.unix newsgroup from December 1986."	"Terminfo:10904051"	1

"Some implementations of terminfo store the terminal description in a hashed database (e.g., something like Berkeley DB version 1.85). These store two types of records: aliases which point to the canonical entry, and the canonical entry itself, which contains the data for the terminal capabilities."	0

"The description contains one or more capabilities, which have conventional names."	"Terminfo data is stored as a binary file, making it less simple to modify than termcap. The data can be retrieved by the terminfo library from the files where it is stored. The data itself is organized as tables for the boolean, numeric and string capabilities, respectively. This is the scheme devised by Mark Horton, and except for some differences regarding the available names is used in most terminfo implementations. X/Open does not specify the format of the compiled terminal description. In fact, it does not even mention the common tic or infocmp utilities. Because the compiled terminfo entries do not contain metadata identifying the indices within the tables to which each capability is assigned, they are not necessarily compatible between implementations. However, since most implementations use the same overall table structure (including sizes of header and data items), it is possible to automatically construct customized terminfo libraries which can read data for a given implementation. For example, ncurses can be built to match the terminfo data for several other implementations."	0

"Like termcap, some of the "string" capabilities represent escape sequences which may be sent to the host by pressing special keys on the keyboard. Other capabilities represent strings that may be sent by an application to the terminal. In the latter case, the terminfo library functions (as does a termcap library) for substituting application parameters into the string which is sent. These functions provide a stack-based expression parser, which is primarily used to help minimize the number of characters sent for control sequences which have optional parameters such as SGR (Select Graphic Rendition). In contrast, termcap libraries provide a limited set of operations which are useful for most terminals."

"Balkans:4829"	"The Balkans ( ), also known as the Balkan Peninsula, are a geographic area in southeastern Europe with various definitions and meanings, including geopolitical and historical. The region takes its name from the Balkan Mountains that stretch throughout the whole of Bulgaria. The Balkan Peninsula is bordered by the Adriatic Sea in the northwest, the Ionian Sea in the southwest, the Aegean Sea in the south, the Turkish Straits in the east, and the Black Sea in the northeast. The northern border of the peninsula is variously defined. The highest point of the Balkans is Mount Musala, , in the Rila mountain range, Bulgaria."	1
"Balkans:4829"	"From classical antiquity through the Middle Ages, the Balkan Mountains were called by the local Thracian name "Haemus". According to Greek mythology, the Thracian king Haemus was turned into a mountain by Zeus as a punishment and the mountain has remained with his name. A reverse name scheme has also been suggested. D. Dechev considers that Haemus (Αἷμος) is derived from a Thracian word "*saimon", 'mountain ridge'. A third possibility is that "Haemus" () derives from the Greek word "haima" () meaning 'blood'. The myth relates to a fight between Zeus and the monster/titan Typhon. Zeus injured Typhon with a thunder bolt and Typhon's blood fell on the mountains, from which they got their name."	0

"The origin of the word "Balkan" is obscure; it may be related to Persian "bālk" 'mud', and the Turkish suffix "an" 'swampy forest' or Persian "balā-khāna" 'big high house'.

"The concept of the Balkan Peninsula was created by the German geographer August Zeune in 1808, who mistakenly considered the Balkan Mountains the dominant mountain system of Southeast Europe spanning from the Adriatic Sea to the Black Sea. The term "Balkan Peninsula" was a synonym for Rumelia in the 19th century, the provinces of the Ottoman Empire in Southeast Europe. It had a geopolitical rather than a geographical definition, which was further promoted during the creation of the Kingdom of Yugoslavia in the early 20th century. The definition of the Balkan Peninsula's natural borders do not coincide with the technical definition of a peninsula; hence modern geographers reject the idea of a Balkan peninsula, while scholars usually discuss the Balkans as a region. The term has acquired a stigmatized and pejorative meaning related to the process of Balkanization, and hence the preferred alternative term used for the region is Southeast Europe."	"Balkans:4829"	1

"The earliest mention of the name appears in an early 14th-century Arab map, in which the Haemus mountains are referred to as "Balkan". The first attested time the name "Balkan" was used in the West for the mountain range in Bulgaria was in a letter sent in 1490 to Pope Innocent VIII by Buonaccorsi Callimaco, an Italian humanist, writer and diplomat. The Ottomans first mention it in a document dated from 1565. There has been no other documented usage of the word to refer to the region before that, although other Turkic tribes had already settled in or were passing through the region. There is also a claim about an earlier Bulgar Turkic origin of the word popular in Bulgaria, however it is only an unscholarly assertion. The word was used by the Ottomans in Rumelia in its general meaning of mountain, as in "Kod̲j̲a-Balkan", "Čatal-Balkan", and "Ungurus-Balkani̊", but especially it was applied to the Haemus mountain. The name is still preserved in Central Asia with the Balkan Daglary (Balkan Mountains) and the Balkan Province of Turkmenistan. English traveler John Morritt introduced this term into the English literature at the end of the 18th-century, and other authors started applying the name to the wider area between the Adriatic and the Black Sea. The concept of the "Balkans" was created by the German geographer August Zeune in 1808, who mistakenly considered it as the dominant central mountain system of Southeast Europe spanning from the Adriatic Sea to the Black Sea. During the 1820s, "Balkan became the preferred although not yet exclusive term alongside Haemus among British travelers... Among Russian travelers not so burdened by classical toponymy, Balkan was the preferred term"."	0

The myth relates to a fight between Zeus and the monster/titan Typhon. Zeus injured Typhon with a thunder bolt and Typhon's blood fell on the mountains, from which they got their name."	0
"On the Adriatic and Aegean coasts the climate is Mediterranean, on the Black Sea coast the climate is humid subtropical and oceanic, and inland it is humid continental. In the northern part of the peninsula and on the mountains, winters are frosty and snowy, while summers are hot and dry. In the southern part winters are milder. The humid continental climate is predominant in Bosnia and Herzegovina, northern Croatia, Bulgaria, Kosovo, northern Montenegro, the Republic of North Macedonia, the interior of Albania and Serbia, while the other, less common climates, the humid subtropical and oceanic climates, are seen on the Black Sea coast of Bulgaria and Balkan Turkey (European Turkey); and the Mediterranean climate is seen on the coast of Albania, the coast of Croatia, Greece, southern Montenegro and the Aegean coast of Balkan Turkey (European Turkey)."	"Most of the area is covered by mountain ranges running from the northwest to southeast. The main ranges are the Balkan mountains (Stara Planina in Bulgarian language), running from the Black Sea coast in Bulgaria to the border with Serbia, the Rila-Rhodope massif in southern Bulgaria, the Dinaric Alps in Bosnia and Herzegovina, Croatia and Montenegro, the Korab-Šar mountains which spreads from Kosovo to Albania and North Macedonia, and the Pindus range, spanning from southern Albania into central Greece and the Albanian Alps, and the Alps at the northwestern border. The highest mountain of the region is Rila in Bulgaria, with Musala at 2,925 m, second being Mount Olympus in Greece, with Mytikas at 2,917 m, and Pirin mountain with Vihren, also in Bulgaria, being the third at 2915 m. The karst field or polje is a common feature of the landscape."	1

"In pre-classical and classical antiquity, this region was home to Greeks, Illyrians, Paeonians, Thracians, Dacians, and other ancient groups. The Achaemenid Persian Empire incorporated parts of the Balkans comprising Macedonia, Thrace, Bulgaria, and the Black Sea coastal region of Romania between the late 6th and the first half of the 5th-century BC into its territories. Later the Roman Empire conquered most of the region and spread Roman culture and the Latin language, but significant parts still remained under classical Greek influence. The Romans considered the Rhodope Mountains to be the northern limit of the Peninsula of Haemus and the same limit applied approximately to the border between Greek and Latin use in the region (later called the Jireček Line). However large spaces south of Jireček Line were and are inhabited by Vlachs (Aromanians), the Romance-speaking heirs of Roman Empire. The Bulgars and Slavs arrived in the 6th-century and began assimilating and displacing already-assimilated (through Romanization and Hellenization) older inhabitants of the northern and central Balkans, forming the Bulgarian Empire. During the Middle Ages, the Balkans became the stage for a series of wars between the Byzantine Roman and the Bulgarian Empires."	0
"Over the centuries forests have been cut down and replaced with bush. In the southern part and on the coast there is evergreen vegetation. Inland there are woods typical of Central Europe (oak and beech, and in the mountains, spruce, fir and pine). The tree line in the mountains lies at the height of 1800–2300 m.

"The term is criticized for having a geopolitical, rather than a geographical meaning and definition, as a multiethnic and political area in the southeastern part of Europe. The geographical term of a peninsula defines that the water border must be longer than land, with the land side being the shortest in the triangle, but that is not the case with the Balkan Peninsula. Both Eastern and Western water cathetus from Odessa to Cape Matapan (ca. 1230–1350 km) and from Trieste to Cape Matapan (ca. 1270–1285 km) are shorter than land cathetus from Trieste to Odessa (ca. 1330–1365 km). The land has a too wide line connected to the continent to be technically proclaimed as a peninsula - Szczecin (920 km) and Rostock (950 km) at the Baltic Sea are closer to Trieste than Odessa yet it is not considered as another European peninsula. Since the late 19th and early 20th-century literature is not known where is exactly the northern border between the peninsula and the continent, with an issue, whether the rivers are suitable for its definition. In the studies the Balkans natural borders, especially the northern border, are often avoided to be addressed, considered as a "fastidious problem" by André Blanc in "Geography of the Balkans" (1965), while John Lampe and Marvin Jackman in "Balkan Economic History" (1971) noted that "modern geographers seem agreed in rejecting the old idea of a Balkan Peninsula". Another issue is the name because the Balkan Mountains which are mostly located in Northern Bulgaria are not dominating the region by length and area like the Dinaric Alps. An eventual Balkan peninsula can be considered a territory South of the Balkan Mountains, with a possible name "Greek-Albanian Peninsula." The term influenced the meaning of Southeast Europe which again is not properly defined by geographical factors yet historical borders of the Balkans."	0

"The First World War was sparked in the Balkans in 1914 when members of Young Bosnia, a revolutionary organization with predominantly Serb and pro-Yugoslav members, assassinated the Austro-Hungarian heir Archduke Franz Ferdinand of Austria in Bosnia and Herzegovina's capital, Sarajevo.

The Ottoman Empire soon joined the Central Powers becoming one of the three empires participating in that alliance. The next year Bulgaria joined the Central Powers attacking Serbia, which was successfully fighting Austro-Hungary to the north for a year. That led to Serbia's defeat and the intervention of the Entente in the Balkans which sent an expeditionary force to establish a new front, the third one of that war, which soon also became static. The participation of Greece in the war three years later, in 1918, on the part of the Entente finally altered the balance between the opponents leading to the collapse of the common German-Bulgarian front there, which caused the exit of Bulgaria from the war, and in turn, the collapse of the Austro-Hungarian Empire, ending the First World War."	0

As examples, for Greeks, Constantine XI Palaiologos and Kolokotronis; and for Serbs, Miloš Obilić and Tzar Lazar; for Montenegrins, Đurađ I Balšić and Ivan Crnojević; for Albanians, George Kastrioti Skanderbeg; for ethnic Macedonians, Nikola Karev and Goce Delčev; for Bulgarians, Vasil Levski, Georgi Sava Rakovski and Hristo Botev and for Croats, Nikola Šubić Zrinjski."	1
"Most of the Balkan nation-states emerged during the 19th and early 20th centuries as they gained independence from the Ottoman Empire or the Austro-Hungarian empire: Greece in 1821, Serbia, and Montenegro in 1878, Romania in 1881, Bulgaria in 1908 and Albania in 1912."

"In 1912–1913 the First Balkan War broke out when the nation-states of Bulgaria, Serbia, Greece and Montenegro united in an alliance against the Ottoman Empire. As a result of the war, almost all remaining European territories of the Ottoman Empire were captured and partitioned among the allies. Ensuing events also led to the creation of an independent Albanian state. Bulgaria insisted on its status quo territorial integrity, divided and shared by the Great Powers next to the Russo-Turkish War (1877–78) in other boundaries and on the pre-war Bulgarian-Serbian agreement. Bulgaria was provoked by the backstage deals between its former allies, Serbia and Greece, on the allocation of the spoils at the end of the First Balkan War. At the time, Bulgaria was fighting at the main Thracian Front. Bulgaria marks the beginning of Second Balkan War when it attacked them. The Serbs and the Greeks repulsed single attacks, but when the Greek army invaded Bulgaria together with an unprovoked Romanian intervention in the back, Bulgaria collapsed. The Ottoman Empire used the opportunity to recapture Eastern Thrace, establishing its new western borders that still stand today as part of modern Turkey."	"During the Cold War, most of the countries on the Balkans were governed by communist governments. Greece became the first battleground of the emerging Cold War. The Truman Doctrine was the US response to the civil war, which raged from 1944 to 1949. This civil war, unleashed by the Communist Party of Greece, backed by communist volunteers from neighboring countries (Albania, Bulgaria and Yugoslavia), led to massive American assistance for the non-communist Greek government. With this backing, Greece managed to defeat the partisans and, ultimately, remained the only non-communist country in the region."	1

"In the 1990s, the transition of the regions' ex-Eastern bloc countries towards democratic free-market societies went peacefully. While in the non-aligned Yugoslavia, Wars between the former Yugoslav republics broke out after Slovenia and Croatia held free elections and their people voted for independence on their respective countries' referenda. Serbia, in turn, declared the dissolution of the union as unconstitutional and the Yugoslavian army unsuccessfully tried to maintain the status quo. Slovenia and Croatia declared independence on 25 June 1991, followed by the Ten-Day War in Slovenia. Till October 1991, the Army withdrew from Slovenia, and in Croatia, the Croatian War of Independence would continue until 1995. In the ensuing 10 years armed confrontation, gradually all the other Republics declared independence, with Bosnia being the most affected by the fighting. The long-lasting wars resulted in a United Nations intervention and NATO ground and air forces took action against Serb forces in Bosnia and Herzegovina and Serbia."	1

"In pre-classical and classical antiquity, this region was home to Greeks, Illyrians, Paeonians, Thracians, Dacians, and other ancient groups. The Achaemenid Persian Empire incorporated parts of the Balkans comprising Macedonia, Thrace, Bulgaria, and the Black Sea coastal region of Romania between the late 6th and the first half of the 5th-century BC into its territories. Later the Roman Empire conquered most of the region and spread Roman culture and the Latin language, but significant parts still remained under classical Greek influence. The Romans considered the Rhodope Mountains to be the northern limit of the Peninsula of Haemus and the same limit applied approximately to the border between Greek and Latin use in the region (later called the Jireček Line). However large spaces south of Jireček Line were and are inhabited by Vlachs (Aromanians), the Romance-speaking heirs of Roman Empire. The Bulgars and Slavs arrived in the 6th-century and began assimilating and displacing already-assimilated (through Romanization and Hellenization) older inhabitants of the northern and central Balkans, forming the Bulgarian Empire. During the Middle Ages, the Balkans became the stage for a series of wars between the Byzantine Roman and the Bulgarian Empires."	0

"The Balkan region was the first area in Europe to experience the arrival of farming cultures in the Neolithic era. The Balkans have been inhabited since the Paleolithic and are the route by which farming from the Middle East spread to Europe during the Neolithic (7th millennium BC). The practices of growing grain and raising livestock arrived in the Balkans from the Fertile Crescent by way of Anatolia and spread west and north into Central Europe, particularly through Pannonia. Two early culture-complexes have developed in the region, Starčevo culture and Vinča culture. The Balkans are also the location of the first advanced civilizations. Vinča culture developed a form of proto-writing before the Sumerians and Minoans, known as the Old European script, while the bulk of the symbols had been created in the period between 4500 and 4000 BC, with the ones on the Tărtăria clay tablets even dating back to around 5300 BC."	0

Dataset Card for `wiki-paragraphs`

Dataset Summary

The wiki-paragraphs dataset is constructed by automatically sampling two paragraphs from a Wikipedia article. If they are from the same section, they will be considered a "semantic match", otherwise as "dissimilar". Dissimilar paragraphs can in theory also be sampled from other documents, but have not shown any improvement in the particular evaluation of the linked work.
The alignment is in no way meant as an accurate depiction of similarity, but allows to quickly mine large amounts of samples.

Supported Tasks and Leaderboards

The dataset can be used for "same-section classification", which is a binary classification task (either two sentences/paragraphs belong to the same section or not). This can be combined with document-level coherency measures, where we can check how many misclassifications appear within a single document. Please refer to our paper for more details.

Languages

The data was extracted from English Wikipedia, therefore predominantly in English.

Dataset Structure

Data Instances

A single instance contains three attributes:

{
  "sentence1": "<Sentence from the first paragraph>",
  "sentence2": "<Sentence from the second paragraph>",
  "label": 0/1 # 1 indicates two belong to the same section
}

Data Fields

sentence1: String containing the first paragraph
sentence2: String containing the second paragraph
label: Integer, either 0 or 1. Indicates whether two paragraphs belong to the same section (1) or come from different sections (0)

Data Splits

We provide train, validation and test splits, which were split as 80/10/10 from a randomly shuffled original data source. In total, we provide 25375583 training pairs, as well as 3163685 validation and test instances, respectively.

Dataset Creation

Curation Rationale

The original idea was applied to self-segmentation of Terms of Service documents. Given that these are of domain-specific nature, we wanted to provide a more generally applicable model trained on Wikipedia data.
It is meant as a cheap-to-acquire pre-training strategy for large-scale experimentation with semantic similarity for long texts (paragraph-level). Based on our experiments, it is not necessarily sufficient by itself to replace traditional hand-labeled semantic similarity datasets.

Source Data

Initial Data Collection and Normalization

The data was collected based on the articles considered in the Wiki-727k dataset by Koshorek et al. The dump of their dataset can be found through the respective Github repository. Note that we did not use the pre-processed data, but rather only information on the considered articles, which were re-acquired from Wikipedia at a more recent state. This is due to the fact that paragraph information was not retained by the original Wiki-727k authors. We did not verify the particular focus of considered pages.

Who are the source language producers?

We do not have any further information on the contributors; these are volunteers contributing to en.wikipedia.org.

Annotations

Annotation process

No manual annotation was added to the dataset. We automatically sampled two sections from within the same article; if these belong to the same section, they were assigned a label indicating the "similarity" (1), otherwise the label indicates that they are not belonging to the same section (0). We sample three positive and three negative samples per section, per article.

Who are the annotators?

No annotators were involved in the process.

Personal and Sensitive Information

We did not modify the original Wikipedia text in any way. Given that personal information, such as dates of birth (e.g., for a person of interest) may be on Wikipedia, this information is also considered in our dataset.

Considerations for Using the Data

Social Impact of Dataset

The purpose of the dataset is to serve as a pre-training addition for semantic similarity learning.

Systems building on this dataset should consider additional, manually annotated data, before using a system in production.

Discussion of Biases

To our knowledge, there are some works indicating that male people have a several times larger chance of having a Wikipedia page created (especially in historical contexts). Therefore, a slight bias towards over-representation might be left in this dataset.

Other Known Limitations

As previously stated, the automatically extracted semantic similarity is not perfect; it should be treated as such.

Additional Information

Dataset Curators

The dataset was originally developed as a practical project by Lucienne-Sophie Marm� under the supervision of Dennis Aumiller. Contributions to the original sampling strategy were made by Satya Almasian and Michael Gertz
