The fairly easy to identify bad tags when they were composed of words that werent included in the dictionary or included characters that were simply inexplicable like a semicolon in the middle of a word. Moreover if the corrected word or phrase occurred in the tag list we could trust the corrected phrase as a potentially good tag and relate the misspelled term to the good tag. Thus this method helps us both filter bad tags misspelled terms and find good tags the spellcorrected term Limitations The biggest limitation with this methodology was that combinations of correctly spelled words or phrases arent necessarily useful for users or the search engine.
For example many of the tags in the database were concatenations Kazakhstan Phone Number of multiple tags where the user spacedelimited rather than commadelimited their submitted tags. Thus a tag might consist of correctly spelled terms but still be useless in terms of search value. Moreover there were substantial dictionary limitations especially with domain names brand names and Internet slang. In order to accommodate this we added a personal dictionary that included a list of the top domains according to Quantcast several thousand brands and a slang dictionary.
While this was helpful there were still several false recommendations that needed to be handled. For example we saw purfect correct to perfect despite being a popculture reference for cat images. is saying as purrfect purrrfect purrrrfect purrfeck etc. Ultimately we had to rely on other metrics to determine whether we trusted the misspelling recommendations. Bid value Method While a tag might be good in the sense that it is descriptive we wanted tags that were commercially relevant. Using the estimated costperclick of the tag or tag phrase proved useful in making sure that the term could attract buyers not just visitors. Benefits One of the great features of this methodology is that it tends to have a high signaltonoise ratio. Most tags.
