Preliminary experimentation with combinations and extensions of forward-looking sentence detection wordlists

Forward-looking sentences are often a subject of studies of financial texts. Detection of such sentences is usually performed with wordlists of inclusive and exclusive keywords that are used as indicators of the forward-looking nature of the sentences at hand. In this paper we describe our assessment of potential improvements of forward-looking sentence detection wordlists by combining them together and by extending them with neighboring words in word-vector representations. Our current results indicate that simple combinations and straightforward extensions of wordlists with vector-space representation neighbors might not be suitable for FLS detection without further methodological improvements.
