Word Embeddings for the Construction Domain
Table 11: Relative classification performance decrease (in %) for all prediction tasks when the compressed representation of injury reports is used rather than their full text (retaining the 30% most highly ranked words as keywords).
['[EMPTY]', 'inj. severity', 'inj. type', 'trade', 'speed-up']
Impact of keyword-based compression. More precisely, compute time in seconds dropped from 9.7K to 1.1K, as measured during 4-fold cross-validation on an 8-core Intel Xeon 2.4GHz machine (within-fold multiprocessing). The associated relative decrease in performance is around 10%. It was measured in terms of overall F1-score computed over observations (not over categories).
