Part of speech (POS) tagger assigns a lexical tag to each word in given sentence. Part of Speech Tagging is a subtask Natural Language Processing Systems, identifies the correct tag according to syntax for each word in corpus (6). Part of speech can be used in many scenarios like information extraction, parsing, word semantic disambiguation, question answering, named entities recognition, virtual chats, scene generation etc. While POS tagging works great for commonly used simple English sentences, but it has not yet achieved good accuracy in the field of interior designing due to its morphological characteristics. This paper compares various POS techniques.
