A multilingual Domain Name System allows users to use Domain Names in non-Unicode or ASCII encodings. An international DNS server (or iDNS server) receives multilingual DNS requests and converts them to a format that can be used in the conventional Domain Name System. When the iDNS server first receives a DNS request, it determines the encoding type of that request. It may do this by considering the bit string in the top-level domain (or other portion) of the Domain Name and matching that string against a list of known bit strings for known top-level domains of various encoding types. One entry in the list may be the bit string for ".com" in Chinese BIG5, for example. After the iDNS server identifies the encoding type of the Domain Name, it converts the encoding of the Domain Name to Unicode. It then translates the Unicode representation to an ASCII representation conforming to the universal DNS standard. This is then passed into a conventional Domain Name System, which recognizes the ASCII format Domain Name and returns the associated IP address.

The present invention provides, among other things, automatic identification of near-redundant units in a large TTS voice table, identifying which units are distinctive enough to keep and which units are sufficiently redundant to discard. According to an aspect of the invention, pruning is treated as a clustering problem in a suitable feature space. All instances of a given unit (e.g. word or characters expressed as Unicode strings) are mapped onto the feature space, and cluster units in that space using a suitable similarity measure. Since all units in a given cluster are, by construction, closely related from the point of view of the measure used, they are suitably redundant and can be replaced by a single instance. The disclosed method can detect near-redundancy in TTS units in a completely unsupervised manner, based on an original feature extraction and clustering strategy. Each unit can be processed in parallel, and the algorithm is totally scalable, with a pruning factor determinable by a user through the near-redundancy criterion. In an exemplary implementation, a matrix-style modal analysis via Singular Value Decomposition (SVD) is performed on the matrix of the observed instances for the given word unit, resulting in each row of the matrix associated with a feature vector, which can then be clustered using an appropriate closeness measure. Pruning results by mapping each instance to the centroid of its cluster.

A method, system, computer program product, and method of doing business by providing improved audio compression wherein an audio stream is securely transformed to an encoded text stream (such as an ASCII, EBCDIC, or Unicode text stream). One or more components which are involved in the transformation process are authenticated. A unique identifier of each such component is included within cryptographically-protected information that is provided for the encoded text stream. A digital signature is preferably used for the cryptographic protection, thereby digitally notarizing the encoded text stream. The authenticity and integrity of the encoded text stream can therefore be verified. In preferred embodiments, the authenticated identities of components performing the transformation can also be determined from the cryptographically-protected information. The encoded text stream will typically require much less storage space than the audio stream, and providing the digital notarization along with the encoded text stream serves to reliably establish evidence of the contents of the audio stream (even though a perfect speech-to-text transformation might not be achieved).

A system, method, and computer program for automatically identifying, parsing, and interpreting tabular data from unstructured documents stored in various formats such as ASCII text, Unicode text, HTML, PDF text, and PDF image format is provided. A set of table identification, parsing / tokenizing, and interpreting / mapping rules are developed with grammar descriptors. These rules are then applied to a set of documents to identify a table, parse the content of the table, and interpret the parsed content, if required, thereby standardizing the tabular data.

A “Character-Level Font Linker” provides character-level linking of fonts via Unicode code-point to font mapping. A lookup table is used to identify glyph-level support for runs of particular characters on a Unicode code-point basis for relative to a set of available fonts. This lookup table enables automatic selection of one or more specific fonts for rendering one or more runs of characters comprising a text string. The lookup table is constructed offline by automatically evaluating glyphs comprising a set of common or default fonts. The table is then used for automatically selecting fonts for rendering text strings. Alternately, the lookup table is generated (or updated) locally to include some or all locally installed fonts. Finally, in another embodiment, if no supporting font is identified in the table for a particular character, the system automatically downloads the necessary glyph from one or more remote servers.

A data structure for specifying the types of constants whose character values are to be converted to Unicode; for specifying which code page or pages are used for specifying the character encodings used in the source program for writing the character strings to be converted to Unicode; and that can be used to perform conversions from SBCS, mixed SBCS / DBCS, and pure DBCS character strings to Unicode. A syntax suitable for specifying character data conversion from SBCS, mixed SBCS / DBCS, and pure DBCS representation to Unicode utilizes an extension to the conventional constant subtype notation. In converting the nominal value data to Unicode, currently relevant SBCS and DBCS code pages are used, as specified by three levels or scopes derived from either global options, from local AOPTIONS statement specifications, or from constant-specific modifiers. Global code page specifications apply to the entire source program. These global specifications allow a programmer to declare the source-program code page or code pages just once. These specifications then apply to all constants containing a request for conversion to Unicode. Local code page specifications apply to all subsequent source-program statements. These local specifications allow the programmer to create groups of statements containing Unicode conversion requests, all of which use the same code page or code pages for their source-character encodings. Code page specifications that apply to individual constants allow a detailed level of control over the source data encodings to be used for Unicode conversion. The conversion of source data to Unicode may be implemented inherently to the translator (assembler, compiler, or interpreter) wherein it recognizes and parses the complete syntax of the statement in which the constant or constants is specified, and performs the requested conversion. Alternatively, an external function may be invoked by a variety of source language syntaxes which parses as little or as much of the source statement as its implementation provides, and returns the converted value for inclusion in the generated machine language of the object program. Alternatively, the conversion may be provided by the translator's macro instruction definition facility.

A mixed text and image layout algorithm capable of supporting Unicode text and arbitrary content definitions for geometric layout with worst case two-pass layout placement procedure. Layout of Unicode text requires a number of distinct processing steps commencing with classification of input characters into contiguous groups of identical directionality, writing system and possibly script (and language) followed by mapping of character groups to glyphs for display purposes followed by a layout taking into account font display characteristics, embedded directionality level and shape of container for layout contents. Layout is best-case achieved in a single layout pass and worst-case in two passes. During layout information is cached to facilitate incremental changes to an existing layout in order to minimize refresh operations for editing display purposes. An optional two-pass operation on the layout result may be used to generate ordered rendering operation to support so-called Z-index display. An optimized Unicode character classification method utilizing reduced memory is also disclosed. Additionally a method to selectively display caret location for mixed font and / or directional text is disclosed.

A system and method is provided for handling the collation of linguistic symbols of different languages that may have various types of compressions (e.g., from 2-to-1 to 8-to-1). A symbol table of the symbols identified as Unicode code points is generated, with each symbol tagged with a highest compression type of that symbol by sorting the compression tables of the various languages. During a sorting operation with respect to a given string, the tag of a symbol in the string is checked to identify the highest compression type of compressions beginning with that symbol, and the compression tables for the language with compression types equal or lower than the highest compression type of the symbol are searched using a binary search method to find a matching compression for the symbols in the string. A common search module is used to perform binary searches through compression tables of different compression types.

System and method for performing Unicode matching for comparing and merging similar data objects having Unicode strings that are equivalent yet not exact matches. Unicode characters are characterized by number of strokes, stroke order, radicals, geometry, phonemes in association with input method editor and keyboard characteristics such as location of a character on an IME or keyboard (or number of GUI interface interactions used in entering the character, e.g., via tapping where “a” on a mobile device keyboard takes 1 tap of a key, “b” takes 2 taps). These characteristics associated with code points and IME's / keyboards are utilized to create subdomains for matching and determining “distance” to other Unicode code points (e.g., number of keyboard keys away). Allows for determining whether close, yet incorrect data entry may have taken place. Enables merging of duplicate data objects into master data object where minor differences or spelling errors introduce actually represent duplicate data.
