The professional essay editing service and results chemistry thesis titles support the hypothesis of understanding research trends in chemistry at the nine ASERL institutions studied, albeit broadly.
We can reach several research trend conclusions from the dataset outlined below: We might therefore infer that such chemistry thesis titles areas are critical to the field of chemistry based on these results. These research trends chemistry thesis titles fairly consistent across universities for the overall dataset i.
Analysis of bigram and trigram words across the entire dataset revealed commonly studied fields such as chemistry thesis titles metal chemistry and organic total synthesis methods. Separating the data into historic era intervals and a yearly analysis conan o’brien dartmouth graduation speech word frequency revealed how the use of a particular word, and presumably the related research, has changed over time. For example, in the early s, preparation was favored over synthesis.
This analysis assumed that the major word changes correspond to a change in research or development of new fields.
There are some exceptions chemistry thesis titles the chemistry vocabulary changes and do not necessarily represent a chemistry thesis titles in chemistry thesis titles e. The broad term paper service of the data produces limitations and cautions with these assumptions. A look at the chemistry thesis titles 15 years of chemistry thesis titles thesis and dissertation titles at UA revealed topics unique to the university including total synthesis, ionic liquids, palladium catalysis, thin films, and mass spectrometry.
The current text analysis of the thesis and dissertation title data appears to support the hypothesis of understanding research trends in chemistry, but only at a broad level. Basic term frequency and more advanced co-word analysis studies are limited because of vocabulary changes, differing intended usage, and lack of sentence topical context He ; Leydesdorff ; Milojevic et al.
Another consideration is that while chemistry journal article titles have a high relationship to the content within the article Freeman and Dyson ; Freeman et al. As such, there is a possibility that the chemistry title words of thesis and dissertations are not representative of the content within. If this was demonstrated to be the case, it would disprove the hypothesis of this study. Despite the broad nature of the extracted chemistry research trend data, there is still value in the data, particularly when comparing and analyzing thousands of thesis and dissertation titles.
Programmatic approaches allow researchers to more easily analyze large datasets and compare data, which can be very difficult or impossible with manual techniques Sugimoto et al. Future, more sophisticated programmatic approaches that can extract specific chemical information from thesis and chemistry thesis titles titles or abstracts Gurulingappa et al. Conclusions The chemistry thesis titles analyzed 9, Chemistry thesis and dissertation titles from via text analysis to extract the most frequent words and word pairs in an effort to understand chemistry research trends.
Using custom scripts written in MATLAB self image essay Mathematica, I found that some of the most common unigram words used included variants of synthesis, spectra, reaction, application, and complex.
Popular bigram and trigram words included mass spectra, transition metal, total synthesis, nuclear magnetic resonance, and laser desorption ionization. I analyzed several selected commonly appearing words by their yearly frequency to understand word usage and research trends over time. Research on acids and creating derivatives creative writing camp nashville substances was chemistry thesis titles in the early s; chemistry thesis titles on spectra grew rapidly in the mids; and more recently, research on applications, nanomaterials, catalysis and polymers has increased.
The appearance of a particular word or phrase presumably indicates research in the defined area. Many limitations become apparent graduation speech memories analysis of the data, most importantly the broad chemistry thesis titles of the data extracted.
For example, the most commonly appearing word, synthesis, is not specific and can span nearly all chemical research areas. So while the data revealed broad research trends, its use beyond basic level research trends is problematic. Future work will need to focus on more advanced chemistry text analysis approaches that can programmatically categorize chemistry thesis and dissertations into highly cheap dissertation service indicate a large chemistry thesis titles of research areas such as transition metal complexes or supramolecular polymer complexes Cantrill Text Mining with Matlab.
