Webb19 feb. 2024 · Imeplements Lesk's Algorithm for word disambiguation using WordNet as a lexical source - LesksAlgorithm/main.py at master · jjnunez11/LesksAlgorithm WebbThe Lesk algorithm is based on the assumption that words in a given "neighborhood" (section of text) will tend to share a common topic. A simplified version of the Lesk algorithm is to compare the dictionary definition of an ambiguous word with the terms contained in its neighborhood. Versions have been adapted to use WordNet.

WebbComputational complexity is a characteristic of almost all Lesk-based algorithms for word sense disam-biguation (WSD). In this paper, we address this issue by developing a simple and optimized variant of the … Webb30 dec. 2024 · Simplified lesk works the same as original lesk but the basic difference is that it removes other stop words from finding overlapping definitions from target words. It produces an accurate result and much faster than original lesk. The following is a simplified lesk algorithm, which uses overlapped function to compute overlapping …

Webb20 aug. 2024 · This paper evaluates simplified Lesk algorithm for Nepali word-sense disambiguation (WSD). Disambiguation is performed by computing similarity between sense definitions and context of ambiguous word. We compute the similarity using three variants of simplified Lesk algorithm: direct overlap, frequency-based scoring, and …
WebbThis paper describes a new Word Sense Disambiguation (WSD) algorithm which extends two well-known variations of the Lesk WSD method.
