“…Content issues: Eysenbach, Powell, Kuss, and Sa (2002) identify several significant content issues for providing online health information that continue to be the subject of reported research (e.g., Pletneva, Cruchet, Simonet, Kajiwara, & Boyer, 2011). The key content issues frequently cited are the sufficiency and availability of content (Soualmia & Darmoni, 2005), permanence (O'Mahony, 1999), accessibility and readability (Berland et al, 2001), and permanence (or currency) (Eysenbach & Köhler, 2002). Sufficiency and availability is particularly important to online health information's sustainability (Soualmia & Darmoni, 2005).…”

Sufficiency and availability is particularly important to online health information's sustainability (Soualmia & Darmoni, 2005). According to the HON Survey (see Pletneva et al, 2011), users rate availability of information as one of the most important factors, which confirms that content of health websites should be sufficient to meet their complex needs.…”

Consumers are increasingly using Internet portals when searching for relevant health information. Despite the broad range of health information portals (HIPs) available, usage problems with such portals are still widely recognized and reported. In this study, we analyzed usage data from an operational health information portal and identified ways in which these problems can be addressed. While previous usage data and log analysis research has focused more on user behaviors, query structures, and human-computer interaction issues, this study covers more comprehensive issues such as content. We describe a taxonomy of usage issues derived from a literature analysis. We describe how we validated and refined the taxonomy based on analyzing the usage data from an operational health portal. Findings from the usage data indicate that a range of content issues exist that lead to unsuccessful searches. The analysis also highlights that users' ineffective information seeking strategies are not well supported by the system's design. We use this taxonomy to propose a usage-driven, consumer-centered approach for dynamic improvements of HIPs. We also discuss the study's limitations and directions for future research.

“…Several add-ons were performed around the MeSH thesaurus to index Web resources instead of scientific articles [9]: super-concepts (or Meta-terms) to optimize information retrieval and categorization, and resource types (organized hierarchically since 1997 vs. MeSH publication types' hierarchy since 2006).…”

“…To evaluate the catalogue and to ensure its continuous relevance, several studies and improvements have been carried out, in order to provide users with the best information. Many tools have been developed: they exploit techniques such as natural language processing, statistics, lexical and background knowledge [ 6 , 7 ], the structure of the MeSH thesaurus [ 8 ], but also simple spelling-correctors based on edit distances [ 9 ].…”

BackgroundThe Catalog and Index of French-language Health Internet resources (CISMeF) is a quality-controlled health gateway, primarily for Web resources in French (n=89,751). Recently, we achieved a major improvement in the structure of the catalogue by setting-up multiple terminologies, based on twelve health terminologies available in French, to overcome the potential weakness of the MeSH thesaurus, which is the main and pivotal terminology we use for indexing and retrieval since 1995. The main aim of this study was to estimate the added-value of exploiting several terminologies and their semantic relationships to improve Web resource indexing and retrieval in CISMeF, in order to provide additional health resources which meet the users’ expectations.MethodsTwelve terminologies were integrated into the CISMeF information system to set up multiple-terminologies indexing and retrieval. The same sets of thirty queries were run: (i) by exploiting the hierarchical structure of the MeSH, and (ii) by exploiting the additional twelve terminologies and their semantic links. The two search modes were evaluated and compared.ResultsThe overall coverage of the multiple-terminologies search mode was improved by comparison to the coverage of using the MeSH (16,283 vs. 14,159) (+15%). These additional findings were estimated at 56.6% relevant results, 24.7% intermediate results and 18.7% irrelevant.ConclusionThe multiple-terminologies approach improved information retrieval. These results suggest that integrating additional health terminologies was able to improve recall. Since performing the study, 21 other terminologies have been added which should enable us to make broader studies in multiple-terminologies information retrieval.
