Today, there are more search queries made on mobile devices than on desktop computers, which has probably been one of the major changes within information search during the past decade, along with the rise of voice search. I was invited to conduct a book review over the summer of ‘Mobile Search Behavior: An In-depth Analysis... Continue Reading →

From a collection of documents to a Graph Visualization in 60 minutes using OpenSource. As a quick exploratory view of a collection of documents too vast to read, these techniques may be useful. Using tools like Python, create n-grams (bi-grams, tri-grams to make it quicker) from your text, terms are nodes, spaces are edges, frequency... Continue Reading →

Geohealth: Text Analytics can be useful to test hypotheses and exploratory data analysis. I've taken the cosine similarity between word vectors of all US States and 'Cadmium' in 100 years of economic geology literature. Above the average shown in orange, below average in blue. This is combined with health data from national databases per US... Continue Reading →

Finding trends and patterns in unstructured text can be possible without combining with other data sources. However, combining derived structured data from text analytics with measured real world data can also lead to differentiating insights. Figure 1 shows the frequency of occurrence of chemical elements in the text of 100 years of the Society of... Continue Reading →

Unsupervised machine learning techniques exploit latent patterns in text (in layman's terms - normally some form of complex word co-occurrence) rather than rules driven by human labelled data. As this is essentially an inductive technique, it can be useful to stimulate ideas and questions that the information professional or geoscientist a priori, may not have... Continue Reading →

I conducted some exploratory search research with geoscientists and engineers in numerous oil & gas companies back in 2014-2015, which I have recently revisited. Unlike lookup/known item search where a user is seeking something specific, an existing need, something they know exists where there is a 'right answer', exploratory search tasks are more loosely defined....

Presenting research on Artificial Intelligence (AI) in academic publishing 26-27 Sep, Washington DC, along with Google, Web of Science, SAGE, Taylor & Francis etc at the Silverchair technology platform conference. https://www.silverchair.com/community/platform-strategies/ In my talk I'll be covering unsupervised machine learning, supervised machine learning, rule based methods (and hybrids) with actual examples of how each technique...

One form of text summarization is by a timeline of some sort. In academic literature, this can help follow a discourse through time using bibliographic reference dates in the body of text. In business literature, this may be more related to events and dates of some activity. In Petroleum Exploration for example, it may refer... Continue Reading →

Excited to be presenting at the Machine Learning in the Subsurface seminar on 20th September in Stavanger, Norway. Organised by the Norwegian Petroleum Directorate (NPD), ConocoPhillips, Repsol, Equinor and AkerBP. More here
