Word process and result table generation

[haohangyan]

Word process branch for entity process(commits after 8/23)

1. Dash Handling: In annotate(), replaced dashes with spaces so that words like A-B are split into A and B, allowing correct recognition of all forms (A, B, and A-B).

Add functions to generate NER output result table (First 6 commits before 8/23)
The output result table contains columns ['text', 'obj', 'obj_synonyms', 'don_article', 'groundings' , 'match']
There are three types of output:

1. Reference('obj', 'obj_synonyms') is None but goundings has values
2. Grounding is None but reference('obj', 'obj_synonyms') has values
3. Both grounding and reference have values
   The 'match' column specifies if there is a match between references and groundings

Old commits are used to be in master branch. Now every commit is in word process branch
