“…Early work on representing word sequences focused on bigram compositionality and considered various simple functions, such as vector addition and averaging (Mitchell and Lapata, 2010;Blacoe and Lapata, 2012), while already Turney (2012) integrated features for more meaningful relations. This early work focused on the representation of specific syntactic constructions and specific number of words and continues to be an ongo-ing research topic: representations of verb phrases (Hashimoto and Tsuruoka, 2016), noun phrases (Baroni and Zamparelli, 2010;Boleda et al, 2013;Dima, 2016), a combination of the two (Zanzotto et al, 2010;Wieting et al, 2015), nounnoun compositionality (Reddy et al, 2011;Hermann et al, 2012;Cordeiro et al, 2018), noun phrases attribute meaning (Hartung et al, 2017;Shwartz and Waterson, 2018), etc. This strand of research covers a variety of approaches ranging from the simple vector arithmetics mentioned to vector-matrix composition operations (Zanzotto et al, 2010;Guevara, 2010;Baroni and Zamparelli, 2010;Boleda et al, 2013), to the functional application of word vectors (Coecke et al, 2010; to RNNs (Wieting et al, 2015) and other supervised (Hartung et al, 2017;Shwartz and Waterson, 2018) or unsupervised approaches (Hermann et al, 2012).…”
