Literature Review Title: Modeling Language Variation and Universals: A Survey on Typological Linguistics for Natural Language Processing 
Chapter Title:  Rule-Based Systems 
1. Abstract of Cited Paper (BIB001):  Abstract This paper explores the ways in which the field of natural language processing (NLP) can and does benefit from work in linguistic typology. I describe the recent increase in interest in multilingual natural language processing and give a high-level overview of the field. I then turn to a discussion of how linguistic knowledge in general is incorporated in NLP technology before describing how typological results in particular are used. I consider both rule-based and machine learning approaches to NLP and review literature on predicting typological features as well as that which leverages such features.

Literature Review:
An interesting example of a rule-based system in our context is the Grammar Matrix kit, presented by BIB002 , where rule-based grammars can be generated from typological features. These grammars are designed within the framework of Minimal Recursion Semantics  ) and can parse a natural language input string into a semantic logical form. The Grammar Matrix consists of a universal core grammar and language-specific libraries for phenomena where typological variation is attested. For instance, the module for coordination typology expects the specification of the kind, pattern, and position of a grammatical marking, as well as the phrase types it covers. For instance, the Ono language (Trans-New Guinea) expresses it with a lexical, monosyndetic, pre-nominal marker so in noun phrases. A collection of pre-defined grammars is available through the Language CoLLAGE initiative BIB001 .
