Correcting Between-Participant Discourse Bias in Comment Classification — Text mining and natural language processing have gained great momentum in recent years, with user-generated content becoming widely available. One key use is comment classification, with much attention being given to sentiment analysis and opinion mining. We find that content extracted from between-participants' discourse is often highly correlated https://papers.ssrn.com/sol3/papers.cfm?abstract_id=2601942
Acceptable bias?: Using corpus linguistics methods with critical discourse analysis corpus linguistics approaches can improve the objectivity of critical discourse analysis research, Taking a recent project which examined the representation of Islam and Muslims in the British press, corpus-driven procedures identified that Muslims tended to be linked to the concept of extreme belief much more http://www.research.lancs.ac.uk/portal/en/publications/-(f059d10e-5292-4379-8d0d-ce729bfe6373).html
Syntactic ambiguity resolution in discourse: Modeling the effects of referential context and lexical frequency. Regression analyses demonstrated that the effects of discourse context at the point of ambiguity (e.g., selected) interacted with the past participle frequency of the ambiguous verb. Reading times were modeled using a constraint-based competition framework in which multiple constraints are immediately integrated during parsing and interpretation.
Framing as a theory of media effects In this paper I systematize the fragmented approaches to framing in political communication and integrate them into a comprehensive model. I classify previous approaches to framing research along two dimensions: the type of frame examined (media frames vs. audience frames) and the way frames are operationalized (independent variable or dependent variable). https://academic.oup.com/joc/article-abstract/49/1/103/4110088
Discourse and Text: Linguistic and Intertextual Analysis within Discourse Analysis diverse approaches to discourse analysis can be enhanced through systematic use of these two forms of analysis, even those which claim a concern with the content rather than the form of texts. It is suggested that textual analysis needs to be based upon a multifunctional theory of language such as systematic-functional linguistics http://journals.sagepub.com/doi/abs/10.1177/0957926592003002004
Strength of Discourse Context as a Determinant of the Subordinate Bias Effect an immediate influence of prior discourse information on lexical processing; and (2) that the strength of discourse constraints can play a governing role in lexical ambiguity resolution https://www.tandfonline.com/doi/abs/10.1080/713755861
Identifying policy frames through semantic network analysis: an examination of nuclear energy policy across six countries The discourse of top-level decision-makers is analyzed to highlight similarities and differences in policy frames and to identify the key policy arguments in the integrated network of all six countries. https://link.springer.com/article/10.1007/s11077-015-9211-3
Collocations in context: A new perspective on collocation networks The idea that text in a particular field of discourse is organized into lexical patterns, which can be visualized as networks of words that collocate with each other, was originally proposed by Phillips (1983). This idea has important theoretical implications for our understanding of the relationship between the lexis and the text and (ultimately) between the text and the discourse community/the mind of the speaker.
A semantic network analysis of associative frames associative frames and the method of semantic network analysis to the PR research field. By building on a more advanced understanding of communication as process of social meaning construction that is embedded in networks of differential relations between different actors, https://www.sciencedirect.com/science/article/abs/pii/S0363811111000944
Semantic Network Analysis as a Method for Visual Text Analytics a method for visual text analytics to support knowledge building, analytical reasoning and explorative analysis. Semantic networks are analyzed with methods of network analysis to gain quantitative and qualitative insights. Quantitative metrics can support the qualitative analysis and exploration of semantic structures. https://www.sciencedirect.com/science/article/pii/S1877042813010227
Detecting contrast patterns in newspaper articles by combining discourse analysis and text mining Text mining aims at constructing classification models and finding interesting patterns in large text collections. This paper investigates the utility of applying these techniques to media analysis, more specifically to support discourse analysis of news reports http://www.jbe-platform.com/content/journals/10.1075/prag.21.4.07pol
Complexity of Word Collocation Networks: A Preliminary Structural Analysis We analyzed graphically and statistically how the global properties of these networks varied across different genres, and among different network types within the same genre. Our results indicate that the distributions of network properties are visually similar but statistically apart across different genres, and interesting variations emerge when we consider different network types within a single genre.
Word co-occurrence networks are one Global topology of word co-occurrence networks: beyond the two-regime power-law of the most common linguistic networks studied in the past and they are known to exhibit several interesting topological characteristics. In this article, we investigate the global topological properties of word co-occurrence networks and, in particular, present a detailed study of their spectrum. https://dl.acm.org/citation.cfm?id=1944585
KeyGraph: automatic indexing by co-occurrence graph based on building construction metaphor. Our algorithm, KeyGraph, is based on the segmentation of a graph, representing the co-occurrence between terms in a document, into clusters. Each cluster corresponds to a concept on which an author's idea is based, and the top-ranked terms are selected as keywords using a statistic based on each term's relationship to these clusters. https://ieeexplore.ieee.org/abstract/document/670375/
Featuring web communities based on word co-occurrence structure of communications: 736 . We present a communication-content based generalization of an existing business-oriented classification of Web communities, using KeyGraph, a method for visualizing the co-occurrence relations between words and word clusters in text. Here, the text in a message board is analyzed with KeyGraph, and the structure obtained is shown to reflect the essence of the content-flow.
The topics are the nodes (words) that tend to co-occur together in the same context (next to each other).
We use a combination of clustering and graph community detection algorithm (Blondel et al based on Louvain) to identify the groups of nodes are more densely connected together than with the rest of the network. They are aligned closer to each other on the graph and are given a distinct color.
We use the Jenks elbow cutoff algorithm to select the top prominent nodes that have significantly higher influence than the rest.
Click the Reveal Non-obvious button to remove the most influential words (or the ones you select) from the graph, to see what terms are hiding behind them.
The most influential nodes are either the ones with the highest betweenness centrality — appearing most often on the shortest path between any two randomly chosen nodes (i.e. linking the different distinct communities) — or the ones with the highest degree.
A structural gap shows the two distinct communities (clusters of words) in this graph that are important, but not yet connected. That's where the new potential and innovative ideas may reside.
This measure is based on a combination of the graph's connectivity and community structure, selecting the groups of nodes that would either make the graph more connected if it's too dispersed or that would help maintain diversity if it's too connected.
These are the latent brokers between the topics: the nodes that have an unusually high rate of influence (betweenness centrality) to their freqency — meaning they may appear not as often as the most influential nodes but they are important narrative shifting points.
These are usually brokers between different clusters / communities of nodes, playing not easily noticed and yet important role in this network, like the "grey cardinals" of sorts.
