The dictionary contains two layers, syntactic and semantic. The syntactic layer describes syntactic and morphosyntactic constraints predicates put on their dependants. The semantic layer shows how predicates and their arguments are involved in a situation described in an utterance. These two layers are connected, representing how semantic arguments can be realised on the surface. Walenty also contains a powerful phraseological (idiomatic) component. Walenty has been created and can be accessed remotely with a dedicated tool called Slowal. In this article, we focus on most important functionalities of this system. First, we will depict how to access the dictionary and how built-in filtering system (covering both syntactic and semantic phenomena) works. Later, we will describe the process of creating dictionary by Slowal tool that both supports and controls the work of lexicographers.

Introduction Walenty (Walenty, 2016) is a comprehensive valence dic- tionary of Polish developed at the Institute of Com- puter Science, Polish Academy of Sciences (ICS PAS) (Przepiórkowski et al., 2014a; Przepiórkowski et al., 2014b). The dictionary is meant to be both human- and machine- readable; in particular, it is being employed by two parsers of Polish—´Swigra1 (Woli´nski, 2004) and POLFIE2 (Pate- juk and Przepiórkowski, 2012). The former, ´Swigra, is an implementation of the DCG (Pereira and Warren, 1980) grammar of Polish of ´Swidzi´nski (1992). The latter, POLFIE, is an implementation of an LFG (Bresnan, 1982; Dalrymple, 2001) grammar of Polish. As these parsers are based on two rather different linguistic approaches, the va- lence dictionary must be sufficiently expressive to accom- modate for the needs of both – and perhaps other to come. The dictionary is based on rigorous rules. First, lexicon en- tries have a strictly defined formal structure. Second, rep- resented syntactic and semantic phenomena should be at- tested in linguistic reality. Last but not least, the structure of the dictionary should enable flexible access. This con- cerns several formats (text, XML, PDF) the dictionary can be exported to as well as the possibility of constructing its sub-dictionaries (e.g., phraseological, concerning particular linguistic phenomena). The assumptions listed above could not be met if Walenty had been created in a traditional way. Therefore, it is stored as a database (with a fairly complicated internal structure) and accessed by a dedicated tool called Slowal, aimed to insert, correct, process and search lexical data. The dictionary is developed remotely, by means of an Inter- net browser. Its entries are elaborated by a highly qualified lexicographers team with precise permissions concerning 1http://zil.ipipan.waw.pl/´Swigra 2http://zil.ipipan.waw.pl/LFG the scope of lexical entries edition.
