Primož Jakopin (pron. Premozh Yacopeen), born 30 June 1949 is a Slovenian computer scientist, most known for his work in the field of language technology.[1]

Early life and education[edit]

Jakopin was born in 1949 in Ljubljana, Slovenia. The family lived in the village of Leskovec pri Krškem, Dolenjska region and in 1956 moved to Ljubljana.[2]

In 1972 he completed a degree in technical mathematics (Numerično računanje singularnih integralov / Numerical Computation of Singular Integrals) at the University of Ljubljana,[3] in 1981 he obtained a master's degree in information sciences with the thesis Entropija imena i prezimena u Sloveniji / On entropy of first names and last names in Slovenia[4] at the University of Zagreb and in 1999 a Ph.D. with the thesis Zgornja meja entropije pri leposlovnih besedilih v slovenskem jeziku / Upper Bound of Entropy in Slovenian Literary Texts,[5] also at the University of Ljubljana.


In high school, he read the book Kraški svet in njegovi pojavi / Karst world and its phenomena by Pavel Kunaver[6] and especially because of its photographs by Bogumil Brinšek, Jakopin became interested in speleology. In 1966 he joined the Društvo za raziskovanje jam Ljubljana / Ljubljana cave exploration society to learn more about caves and to participate in exploration of new caves.[7] He observed that the principal cave parameters, obtained from the cave survey, length and depth, also used to compare and classify caves, for instance in the List of longest caves and in the List of deepest caves, do not represent cave size properly as caves are 3D objects with volume as their main and most noticeable feature.[8] In 1972, at the 6th Yugoslav congress of speleology, he proposed volume as the main cave parameter in the paper O numeričnem vrednotenju kraških objektov / Numerical Valuation of Objects on Karst.[8]

3D Model of the Main Gallery in Skednena jama Cave

In 1974 he made a 3D model for approximation of cave space, based on a series of connected polygonal cross sections and used it to make a 3D survey of Skednena jama cave, a fossil ponor at the northern rim of the Planinsko polje karst field in Slovenia. By 1979 he developed a computer program to support the 3D model, to computate its vertice coordinates and to calculate the model (and cave) parameters: length, surface and volume. In 1981 Jakopin published the results for Skednena jama cave in the paper Macrostereological Evaluation of Cave Space. The model had 305 vertices, 51 cross sections, total length was 205 m, surface area 8900 m2 and volume 6.500 m3.[9]

Computational linguistics[edit]

He was a senior lecturer at the Department of Comparative and General Linguistics, Faculty of Arts, University of Ljubljana. His subjects of instruction are language technologies with stress on Lemmatisation.[10] From 2001 to 2012 he was the Head of the Corpus Laboratory at the Fran Ramovš Institute of Slovene Language (within the Scientific Research Centre of the Slovenian Academy of Sciences and Arts).[11] He participated in a number of European projects on language resources.[12]

His major pieces of software: IBIS (Digital DEC 10, 1981), INES (Sinclair ZX Spectrum, 1985),[13][14] STEVE (ATARI ST, 1987-1992),[15] EVA for DOS, 1992- and Windows 9X/2000/XP, 1996-,[16] NEVA - Windows server search engine, 1999-. From 1992 to 1994 he supervised the transfer of the Standard Slovenian Dictionary (SSKJ) from printed to electronic version (EVA OCR, DOS version). In 1997 he wrote the first part-of-speech tagger for Slovene texts. In 1999 he started an Internet text corpus, with a concordance service and linked wordform and reversed wordform frequency dictionaries. It is now available as Nova beseda (New word).

His father Franc Jakopin was a Slovenian slavist, lexicographer and onomatologist[17] his mother Gitica Jakopin was a translator, writer and a poet,[18] his brother Japec Jakopin is a yacht concept designer and his brother Jernej Jakopin is a naval architect.
