CLEARPOND provides a user-friendly, web-based interface for obtaining Dutch, English, French, German, and Spanish phonological and orthographic neighborhood densities (or, PONDs). The search function allows users to search for POND information in any of the five languages using single word queries or providing full lists of words. CLEARPOND provides a number of important psycholinguistic measures, such as neighborhood density and neighborhood frequency, both for within-language neighbors and foreign-language neighbors. With user-controlled output selection, researchers can choose the output parameters that are most relevant. In addition to allowing users to acquire data for specific words, CLEARPOND can also search by features so that researchers can generate new lists of words that meet precise criteria, such as a specific range of neighborhood sizes or lexical frequency (as provided by the Subtlex databases). Furthermore, multiple filters can be applied simultaneously, providing greater control for stimuli creation. Users also have the option of exporting their results directly to a text file, making it easy to create downloadable documents containing pertinent psycholinguistic measures for all of their stimuli. In addition to the web-based interface, more comprehensive lists containing of all of the information provided by the database are available for download, so that the entire CLEARPOND database can be accessed offline.
