The oldest preserved dictionaries were in form of cuneiform tablets with Sumerian-Akkadian word-pairs and are dated 2300 BC. Grammars are \"younger\". Among the first were grammars for Sanskrit attributed to Yaska (6th century BC) and P\u0101\u1e47ini (6-5th century BC). In Europe the oldest known grammars and dictionaries date from the Hellenic period. The first one was Art of Grammar by Dyonisus Thrax (170-90 BCE), in use in Greek schools still some 1,500 years later. Until recently, these tools were used for the same purposes as before -teaching and translation, and ipso facto were supposed to be interpreted by humans. The formal rigor was considered of secondary importance. The situation changed recently with development of computer-based information technologies. For machine language processing (as machine translation, text and speech understanding, etc.) it appeared crucial to adapt language description methodology to the technologyimposed needs of precision. Being human-readable was not enough, new technological age required from grammars and dictionaries to become machine-readable. New concepts of organization of language description for better facing technological challenges emerged. One among them was the concept of lexicon-grammar. This paper addresses two cases. Firstlanguages with a rich linguistic tradition and valuable preexisting language resources, for which the methods described in this paper will be easily applicable and may bring interesting results. 1 We do not believe that basic linguistic research is avoidable on the base of technological solutions only. (See the historical statement addressed by Euclid of Alexandria Among Indian languages this will be the case of Sanskrit, Hindi and many other. On the other hand, a multitude of languages in use on the Indian subcontinent do not dispose of such a privileged starting position. In this case, in order to benefit from the methodology we describe in this paper, an effort must first be done to complete existing gaps. This is a hard work, and the paper, we hope will give some idea on the priorities on this way. Still, an important basic research effort will be necessary 1 .", "cite_spans": [ { "start": 1600, "end": 1601, "text": "1", "ref_id": null } ], "ref_spans": [], "eq_spans": [], "section": "Introduction", "sec_num": "1." }, { "text": "Development of computational linguistics and resulting language technologies made possible passage from the fundamental research to the development of real-scale applications.

Within this approach, it is natural to keep syntactic and semantic information stored as a part of lexicon entries together with other kinds of information (e.g. pragmatic). This principle applies first of all to verbs, but also to other words which \"open\" syntactic positions in a sentence, as e.g. certain nouns, adjectives and adverbs.

Since real world applications invariably require larger linguistic coverage, the number of entries in electronic dictionaries inevitably increases. The second reason lies in the tendency to insert an increasing amount of linguistic information into a lexicon. (\u2026) In the eighties, new attempts were made with an emphasis on grammars, but an engineering problem arose: how to manage a huge set of more or less interdependent rules. The recent tendency is to organize the rules independently, to call them syntactic/semantic properties, and to store this information in the lexicon.

Positive results obtained within this project demonstrated potential usefulness of the lexicon-grammar approach for so far less-resourced languages, Indo-European or not.

In addition to information typically provided in system of Polish strongly marks Polish syntax; as the declension case endings characterize the function of the word within the sentence, therefore the word order is more free than in, e.g., Romance or Germanic languages where the position of the word in a sentence is meaningful. Main representatives of the Polish declension system are nouns, but also adjectives, numerals, pronouns and participles. Polish inflected forms are created by combining various grammatical morphemes with stems. These morphemes are mainly prefixes and suffixes (endings). Endings are considered as the typical inflection markers and traditional classifications into inflection classes are based on ending configurations. Endings may fulfil various syntactic and semantic functions at the same time. A large variety of inflectional categories for most of parts of speech is the reason why inflection paradigms are complex and long in Polish. For example, the nominal paradigm has 14 positions, the length of the verbal paradigm is 37 and the length of the adjectival one is 84 (Vetulani, G. 2000) . 5 Some of the outcomes of these project are described in (Vetulani, G. 2000 ).", "cite_spans": [ { "start": 74, "end": 92, "text": "(Vetulani, Z. 1988", "ref_id": null }, { "start": 93, "end": 113, "text": "(Vetulani, Z. , 1997", "ref_id": null }, { "start": 1281, "end": 1300, "text": "(Vetulani, G. 2000)", "ref_id": null }, { "start": 1303, "end": 1304, "text": "5", "ref_id": null }, { "start": 1360, "end": 1378, "text": "(Vetulani, G. 2000", "ref_id": null } ], "ref_spans": [], "eq_spans": [], "section": "Lexicon-Grammar of Polish", "sec_num": "4." }, { "text": "dictionaries we managed to explore structural, as well as morpho-syntactic-and-semantic information directly stored with predicative words, i.e. words which are surface manifestation of sentence predicates.

The content of lexicon-grammar entries informs about the structure of minimal complete elementary sentences supported by the predictive words, both simple and compound. This information may be precious in order to substantially speed-up sentence processing 6 (see e.g. Vetulani, Z. 1997) .

In Princeton WordNet like systems basic entities are classes of synonyms (synsets) related by some relations of which the most important are hyponymy and hyperonymy. Synsets may be considered as ontology concepts with the advantage of being direcly linked to words. We started the PolNet project in 2006 13 at the Department of Computer Linguistics and Artificial Intelligence of Adam Mickiewicz University and its progress continues. The resource development procedure was based on the exploration of good traditional dictionaries of Polish and the use of available language corpora (e.g. IPI PAN Corpus; cf." } } } }
