Co-occurrence networks of Twitter content after manual or automatic processing. A case- study on “gluten-free”
Gathering information from social networks such as Twitter has emerged to obtain spontaneous and direct opinions of users about a topic. This study focuses on using co-occurrence networks to analyse Twitter information. The objectives were to study the impact of text pre-treatment (codification based in qualitative analysis or just pre-cleaning) and to apply co-occurrence networks for analysing what is said on Twitter about specific topics like “gluten-free”. As such, 16,386 tweets in Spanish containing terms “sin-gluten” and “gluten-free” were collected. A subset of 3,000 tweets was used to make co-occurrence networks two ways: i) from the manually coded text and ii) from pre-cleaned text. Results indicate that the co-occurrence network from pre-cleaned text provides meaningful information showing structure and relevance for terms like the network from coded text. The whole set of tweets was used to explore Twitter information about gluten-free, showing users share information about products, occasions, social situations, and places but also to product characteristics, sensations, and diet or health issues related to the products. Five product categories, critical for the lack of gluten (bread, cake, cookie, beer, and pizza) occupied most tweets, and according to the related terms were intended to recommend how to get (buying or cooking) these gluten-free products and to exhibit what (how, when, and where) they prepare and eat. These aspects were different among products and separated co-occurrence networks allowed better identification.
