Content Recommendation Using Zemanta

  1. 1. Content recommendation using Zemanta Irina Hu anu Alexandru Ioan Cuza University, Computer Science, Computational Linguistics ( 2nd year), Faculty of Letters graduate Abstract.Zemanta is a tool that helps a blog user to better manage and represent the content he or she is writing. The application is developed so that links, pictures, images and tags to be easily added and discovered : “Zemanta is a tool that looks over your shoulder while you blog and gives you tips and advice, suggests related content and pictures and makes sure your posts get promoted as they deserve to be.”1 Zemanta has its good and bad sides, although it helps you to easily find the material you need to promote the blog, it can be quite useless if you choose to write your blog in another language than English and at times it doesn’t return very accurate results. 1. Introduction Zemanta supports supports blog platforms like, Self-hosted 2.1+,, TypePad, Ning, MySpace, LiveJournal, MovableType, Tumblr, Drupal, Joomla. Depending on the platform the blogger uses, Zemanta can be installed as a plugin or as an extension. However, after installing it in your browser, things are easy, just open your blog’s dashboard and this little tool will state its presence. Just like in the picture. Fig. 1 Zemanta tool 1 - learn
  2. 2. As you can see Zemanta is placed in the right corner of your dashboard and it displays photos, images, related articles that have connection with what the blogger is writing at the moment. The search results are given on the basis of a comparison. The tool scans the text while you are typing it, selects the words that seem to have bigger relevance and goes online searching for links, photos and related articles. Most of the time it returns results that point to websites like Wikipedia, Flickr or Google Maps. The main reason for this is the fact that the application is not yet fully developed, but, in the future, the authors promise us a more complex semantic linking2. 2. Positive aspects At first sight, Zemanta doesn’t seem a very attractive and useful tool. You say to yourself that searching for some photos and related articles it’s not such a big deal. And, in fact, it isn’t, but why should you do it, when someone else can do it for you. It also helps the user to save up time, because the search is performed during the writing activity. Another plus is the drag-and-drop capabilities and the simple tagging. If the user discovers a photo or image that thinks to be appropriate for his/her site, just drags it inside the editor or double-clicks on the picture and that’s it. The links and tags are displayed under the editor and are button-like, a simple click will automatically link you to a reference or tag your article. Fig. 2 The links discovered by Zemanta (orange display) 2 „Placing semantically smart links is a hard problem. We decided to give you this tool and let you help us shape its future development. We will be suggesting links to many more sources in the future. Please share your expectations with us.” - faqid-10
  3. 3. Fig.3 The related photos returned by Zemanta and the Search option. When it comes to copywriting, Zemanta displays the source of a photo or article, thus protecting the user. We also need to add that this tool searches only images that display their original author, hence the irrelevant search results it sometimes offers. It also supports quoting, transferring the content from one blog to another and always linking the quote to the original site, preventing plagiarism. In other words that is the utility of the REBLOG button.
  4. 4. An interesting feature of this application is the capacity of previewing the site reference of a link, just by hoovering the cursor over it. The user will choose to visit or not the web page by simply inspecting the balloon preview3. 3. Negative aspects Zemanta has limited functionality when it comes to other languages than English. We tried to use this application on a blog post written in Romanian. The only valid results were the pictures, but those too unsatisfying, because it couldn’t find anything relevant for our topic4. Another aspect that gets in the way of pretentious blog users is related to the design of the post. The photos you drag and drop in the editor cannot be moved or rearranged and the same happens when we talk about the related articles Zemanta discovers. The latter can be added only at the end of the article without having the possibility to move them, thus this tool forces the user to accept only its terms. The most problematic aspect seems to be related to its main functionality: the searching proccess. Most of the time the results are not relevant, especially when it comes to related articles and when your post is short and concise. We noticed that even works listed in the Wikipedia database were omitted, thus needless to say that Zemanta should suffer some important makeover. 4. Zemanta and DBpedia5 Zemanta is used as a tagging tool, retrieving most of the information from Wikipedia. The Dbpedia project extracts knowledge from Wikipedia and organises it in a logical model, making the Wikipedia knowledge more accesible world wide. Zemanta uses this platform to query Wikipedia database and return the most adequate tags and links. Zemanta and Dbpedia are also connected to Linked Galaxy 6. Zemanta identifies the semantic entities in the text written by the blogger and uses Linked Galaxy to connect with Dbpedia, this way the queries are more sophisticated and interesting references might be discovered. 5. Final remarks Overall, Zemanta seems to be a helpful device for active bloggers that cannot waste time searching the web for visual aids and suggestive information to complete their posts. The tool is fast, offers a good functionality and acceptable search results. For a better functionality of this little device the user should write longer articles, the bigger the wordbank, the merrier the results. The shortcomings are connected with some limits of the application, like the impossibility to create your own design of the post (he photos can be placed only on the right or on the left of the text, but not both at once) or the narrow laguage option, the user is forced to stop only at English, for other idioms the search returns erroneous results. 3 Engage Audience Longer, 4 5 6
