Abstract
The article presents the experience of developing computer ontology as one of the tools for Tibetan idioms processing. A computer ontology that contains a consistent specification of meanings of lexical units with different relations between them represents a model of lexical semantics and both syntactic and semantic valencies, reflecting the Tibetan linguistic picture of the world. The article presents an attempt to classify Tibetan idioms, including compounds, which are idiomatized clips of syntactic groups that have frozen inner syntactic relations and are often characterized by omission of grammatical morphemes; and the application of this classification for idioms processing in computer ontology. The article also proposes methods of using computer ontology for avoiding idioms processing ambiguity.

Notes
- 1.
Following the definition of Krippendorf, combinatorial explosion is understood here as a situation “when a huge number of possible combinations are created by increasing the number of entities which can be combined” [4]. As applied to parsing, these are cases of exponential growth in the number of parsing versions as the length of the parsed text and, thus, the amount of its parsed ambiguous fragments increase.
- 2.
These 3 interpretations represent 3 groups of versions that arose only because of incorrect combinations of adjuncts, each group consisting of 18 versions (2 for ring-lugs, multiplied by 3 for dpal-yon and by 3 for mdzes-chos rig-pa). Thus, the total amount was 54.
- 3.
Example (9) has 32 versions of parsing. These 3 interpretations represent groups of versions that arose only because of incorrect designating of subject for the verb bsu ‘to invite’.
