Lähisanaikkuna

Lähisanaikkuna, also known as the "collocation window," is a concept in computational linguistics and natural language processing that refers to the set of words that frequently co-occur with a given word within a specific range of positions in a text. This range is typically defined by a fixed number of words before and after the target word, creating a "window" of context around it.

The size of the collocation window can vary depending on the specific application or research question. For example, a window of size 2 would include the two words immediately before and after the target word, while a window of size 5 would include five words before and five words after.

Collocation windows are used in various linguistic and computational tasks, such as:

1. Identifying meaningful word pairs or phrases (collocations) that occur together more frequently than expected by chance.

2. Analyzing the semantic relationships between words based on their co-occurrence patterns.

3. Improving the performance of natural language processing models by incorporating contextual information.

Lähisanaikkuna is an essential tool for understanding the distributional properties of words in a language and for developing more accurate and efficient language processing systems.
