The work presented in this paper concerns automatic information retrieval and extraction in precise field of electronics based on linguistic knowledge. The extraction and the filtering of data is carried out automatically by methods based on the construction of local grammar. To carry out an automatic search for the events in the corpus, a linguistic base, for example the base of the graphs, was created. A comparison of methods is given.
